The Coverage tab shows how much of your code the test suite actually exercises. Coverage is collected as part of a test run — so until you’ve run the suite, there’s nothing to show here yet.

Collecting coverage
When your test framework is configured but the suite hasn’t run, Coverage shows a No coverage collected yet state. Click Run tests to execute the suite with coverage — progress streams live in the Tests tab, and once the run completes, your coverage results land here.
Coverage and test results come from the same run. Running the suite populates the Tests view with pass/fail results and this view with coverage at the same time.
Generating more tests
If you’d like broader coverage before running, generate additional tests first with the Generate more link, then run the suite. More tests mean more of your code is exercised, which is reflected in the coverage collected here.
Coverage is most useful as a trend — run the suite after meaningful changes to see whether newly added code is being verified, not just the code you started with.
